| Sumario: | Urban vegetation is important to mitigate environmental problems caused by disordered urbanization and to provide quality of life to the population. The objective of the research was to map and analyze the urban green areas of Campos dos Goytacazes, Brazil. Therefore, satellite images and fieldwork were used to identify and validate green areas. In the Geographic Information System environment, data from green areas from the 2010 IBGE demographic census, and other data such as hydrography and limits of census sectors were integrated. With that, it was possible to estimate indexes and build thematic maps that supported the analyses. The survey found a percentage of green areas of 2.5%, an index of urban green areas per inhabitant of 11.26 m² / inhab., and public green areas for recreation of 0.66 m² / inhab. In addition, 70% of the census sectors do not have green areas. We concluded that the municipality has a deficit of urban green areas, and that there is a need to implement them, mainly public areas intended for recreation in densely populated places. |
